Definitions

  • the present invention relates to rollers or analogous devices for the treatment of fibrous materials with the application of heat and/or solvents. More particularly, the invention relates to improvements in rotary devices which can be used to reinforce or strengthen selected portions of layers, webs, sheets or panels of nonwoven fibrous material as a result of controlled and oriented application of heat and/or suitable solvents.
  • protrusions which extend outwardly from the peripheral surface of a cylindrical body.
  • the protrusions may be in the form of ribs or in the form of discrete protuberances of relatively small width and length, as considered in the circumferential and axial directions of the cylindrical body.
  • the cross-sectional area of the base of each protrusion in the region of the peripheral surface is larger than the cross-sectional areas which are more distant from the peripheral surface.
  • rollers of the above outlined character are often used to enhance the absorbency of layers of fibrous material which can be used as absorbent pieces of textile material or the like.
  • the taper of such protrusions is quite pronounced so that each protrusion resembles a strongly tapering pyramid or a similar geometric body. This is intended to reduce the likelihood of development of undercuts during the engraving of a cylindrical body for the purpose of making protrusions thereon.
  • such formation of protrusions also brings about serious drawbacks, for example, because the fibers are likely to be bonded to each other in those regions which are adjacent to the facets or flanks of the protrusions, i.e., not only in the regions of the tips or outermost portions of such protrusions.
  • the useful life of such conventional rollers is relatively short because the protrusions cannot be ground a large number of times since each grinding entails a pronounced increase in the areas of top lands of the protrusions with attendant much more pronounced transfer of heat between the tips of the protrusions and the adjacent fibers. Still further, repeated grinding of the protrusions entails a pronounced reduction of the volume of the grooves between neighboring protrusions so that such grooves can accommodate a smaller number of fibers when the rollers of the just described conventional character are in actual use.
  • An object of the invention is to provide a novel and improved device for heat- and/or solvent-treatment of nonwovens or the like which can stand much longer periods of use than all heretofore known devices of such character.
  • Another object of the invention is to provide a device which can be repeatedly ground or subjected to an analogous material-removing treatment without unduly affecting its action upon a fibrous material.
  • a further object of the invention is to provide a rotary roller-shaped device which can be used in existing textile machines as a superior substitute for heretofore a highly desirable directed flow of heat energy to selected portions of treated material.
  • An additional object of the invention is to provide a device whose protrusions are configurated, dimensioned and distributed in a novel and improved way.
  • Another object of the invention is to provide a device wherein the likelihood of excessive heating of those portions of a nonwoven textile material which do not require, or which should not be subjected to, intensive heating is much less pronounced than in heretofore known reinforcing devices for nonwovens or the like.
  • An ancillary object of the invention is to provide a textile material which has undergone a treatment with a device of the above outlined character.
  • Another object of the invention is to provide a novel and improved method of transmitting heat to selected portions of textile materials.
  • the invention resides in the provision of a device for heat- and/or solvent-treatment of fibers in nonwovens or the like.
  • the improved device comprises a rotary body having a substantially cylindrical peripheral surface and a plurality of neighboring protrusions in the form of nobs or analogous protuberances which extend outwardly beyond the peripheral surface of the rotary body.
  • Each protrusion includes an outer or first section which is more distant from the peripheral surface of the rotary body and has a top land in the form of a platform or the like, and a second section between the peripheral surface and the first section.
  • the first sections of the protrusions have first facets each of which makes with the respective top land a first acute angle
  • the second sections of the protrusions have second facets each of which makes with the respective top land a second acute angle which is smaller than the first acute angle.
  • Each protrusion can have a substantially rectangular, square or rhomboidal outline.
  • the first angle can be between 20° and 90°, preferably between 80° and 88°, and most preferably about 86°.
  • the second angle can be between 45° and 75°, preferably approximately 60°.
  • the height of the first sections need not exceed and can be less than the height of the respective second sections.
  • the presently preferred ratio of the heights of first and second sections of each protrusion is approximately three-to-five.
  • the distance between the second sections of two neighboring protrusions in the region of the peripheral surface of the rotary body need not exceed half the distance between the top lands of such neighboring protrusions.
  • the distance between the second sections of two neighboring protrusions in the region of the peripheral surface of the rotary body need not exceed half the height of a protrusion, as measured radially of the rotary body.
  • the distance between those portions of the first sections of two neighboring protrusions which are nearest to the respective second sections at least equals the width of such portions of first sections, as measured in the circumferential direction of the rotary body.
  • the protrusions can form annuli which extend circumferentially of the rotary body or spirals which extend around the rotary body.
  • each section of each protrusion can resemble the frustum of a cone or a pyramid, each protrusion can have more than two sections, and the taper of each section which is nearer to the peripheral surface of the rotary body is more pronounced than the taper of each section which is outwardly adjacent thereto.
  • FIG. 1 is a fragmentary elevational view of a device which embodies one form of the invention.
  • FIG. 2 is an enlarged sectional view of two neighboring protrusions and of the adjacent portion of the cylindrical body of the device which is shown in FIG. 1.
  • the device which is shown in FIG. 1 is a roller which comprises a rotary cylindrical body 1 having a peripheral surface 1a (see FIG. 2) and provided with several circumferentially extending annuli or spirally arranged rows of protrusions 3 in the form of twin pyramidal frusta each of which has a flat or substantially flat top land 2.
  • Each protrusion 3 includes several sections including a first or outer section 3a which is immediately adjacent to the respective top land 2 and a second or inner section 3b which is disposed between the first section 3a and the peripheral surface 1a of the cylindrical body 1.
  • the illustrated device cooperates with a similar or identical device for reinforcement of fibers as a result of the application of heat and/or solvents in a manner not forming part of the present invention.
  • the protrusions 3 can serve to weld the adjacent portions of fibers as a result of transfer of heat from the top lands 2 into the material which is adjacent thereto.
  • Each first section 3a is flanked by four facets 4a and each such facet makes with the respective top land 2 a relatively large acute angle 90° minus alpha.
  • the reference character E denotes a plane which extends substantially radially of the body 1, i.e., substantially at right angles to the planes of the adjacent portion of the peripheral surface 1a and of the corresponding top land 2, and the facet 4a which is immediately adjacent to such plane makes therewith an angle alpha.
  • the angle between a facet 4a and the respective top land 2 can be between 20° and 90° and preferably between 80° and 88°, most preferably approximately 86°.
  • the acute angles (90° minus beta) between the facets 4b of the second sections 3b and the respective top lands 2 are smaller than the angles 90° minus alpha.
  • the angle beta between each facet 4b and the adjacent plane E can be in the range of between 15° and 45°, preferably approximately 30° (i.e., the angle 75° minus beta is between 45° and 90°), preferably approximately 60°.
  • each of the sections 3a and 3b constitutes the frustum of a pyramid.
  • the reference character 5 denotes in FIG. 2 the region where the respective second section 3b merges into the cylindrical body 1 of the improved device.
  • protrusions 3 ensures highly satisfactory and accurately oriented transfer of heat from the body 1 to the top lands 2 of the first sections 3a and thence into the adjacent fibrous material. Moreover, such configuration of protrusions 3 contributes to their stability, especially to pronounced resistance to the action of transverse forces, e.g., forces acting tangentially or circumferentially of the cylindrical body 1.
  • Each of the protrusions 3 preferably exhibits a polygonal (particularly square, rectangular or rhomboidal) outline.
  • the aforementioned selection of angles 90° minus alpha and 90° minus beta exhibits the advantage that the protrusions 3 can be readily formed in available machines, e.g., in suitable engraving machines.
  • FIG. 2 shows that the height 4a' of the first sections 3a (as measured radially of the body 1) at most equals but is preferably somewhat less than the height (4b') of the respective second sections 3b.
  • a presently preferred ratio of the heights 4a' to 4b' is approximately three-to-five.
  • Such dimensioning of the sections 3a and 3b contributes stability and more satisfactory thermal conductivity of the protrusions 3.
  • the distance a between the bases 5 of two neighboring protrusions 3 is much less (preferably less than one-half) than the distance A between the respective top lands 2.
  • the distance a can approximate but can be at least slightly less than half the height of a protrusion 3, as measured radially of the body 1.
  • the distance C between those portions of the first sections 3a of two neighboring protrusions 3 which are nearest to the respective second sections 3b preferably equals, approximates or slightly exceeds the width B of the adjacent radially innermost portions of first sections 3a, as measured circumferentially of the body 1 (it is assumed that the protrusions 3 shown in FIG. 2 form part of an annulus of protrusions which extend substantially circumferentially of the body 1).
  • Such dimensioning of the channels or grooves between the neighboring protrusions 3 contributes to a harmonic configuration of the channels and provides ample room for the filaments to enter between neighboring protrusions to thus avoid welding of fibers (or to reduce to a minimum the welding of fibers) in locations where the fibers should remain unattached to each other. This also allows for predictable and rapid separation of the improved device from the treated material.
  • the improved device can be subjected to a surprisingly large number of consecutive grinding operations without unduly altering the transfer of heat between the protrusions 3 and the material which requires treatment. This is due to the aforediscussed feature that the angles 90° minus alpha are larger than the angles 90° minus beta, i.e., that the taper of second sections 3b in directions from the peripheral surface 1a toward the respective top lands 2 is more pronounced than the taper of the first sections 3a.
  • the improved device accomplishes several apparently contradictory objects, namely it can be ground again and again without adversely affecting the transfer of heat from the top lands 2 to the adjacent fibrous material.
  • the relatively large and sturdy sections 3b enhance the stability of the protrusions 3 which is especially desirable in the course of a grinding operation because the grinding tool is less likely to break or otherwise separate the protrusions from the rotary body 1 of the improved device.
  • the facets 4a exhibit the advantage that they are less likely to transfer heat to adjacent fibers which would entail bonding in regions where the bonding is not required or is outright damaging to the ultimate product. This holds true even if the fibrous material which is being treated by the improved device is relatively thick. All in all, the useful life of the improved device is much longer than that of heretofore known devices which are used for analogous purposes. This is important because the engraving of protrusions 3 is a costly procedure.
  • the two devices are mounted in such a way that their axes are parallel to one another.
  • the helices which are formed by the protrusions of one device cross the helices which are formed by the protrusions of the other device so that they subject a fibrous material therebetween to a spot welding action.
  • the protrusions can constitute circumferentially extending ribs or spirals with circumferentially or helically extending channels or grooves therebetween.
  • the discrete protrusions form several helically arranged rows with one set of rows intersecting the other set of rows. This can be readily seen in FIG. 1.
